On the other hand, components indicated by solid lines in FIG. 5 represent components installed on the mounting surface, and components indicated by dotted lines represent components installed on the floor surface.

Referring to FIG. 4, the filter device 130 may be installed on a bottom surface of an installation space, purify the air in the storage space, and then discharge it back to the storage space, thereby purifying the air inside the storage space. More specifically, the filter device 130 includes a housing 131, a suction fan 132 and a discharge fan 138, filter units 135, 136, 137 and a controller 134.

The housing 131 houses the suction fan 132, the discharge fan 138, the filter parts 135, 136, 137, and the controller 134 therein. The controller 134 controls the operation of the filter device 130 and does not necessarily need to be disposed inside the housing 131.

The suction fan 132 is disposed on the side of the first opening 111a inside the housing 131 and operates to suck air in the storage space from the first opening 111a. In addition, the exhaust fan 138 is disposed on the side of the second opening 111b in the housing 131 and operates to discharge the purified air through the second opening 111b. The filter units 135, 136, 137 are disposed between the suction fan 132 and the discharge fan 138 to purify the air.

Meanwhile, the first opening 111a and the housing 131 are connected through a suction line 131a, and the housing 131 and the second opening 111b are connected through a discharge line 131b. The suction line 131a may be a pipe, and the outer circumferential surface of the suction line 131a is surrounded by an insulating material to prevent condensation from occurring due to a temperature difference inside or outside the line or a sudden change in temperature when air is sucked.

In this way, the suction fans 132 and the discharge fans 138 are provided on both sides of the housing 131, so that the air in the storage space can be circulated more quickly. More specifically, the suction fan 132 is disposed adjacent to the first opening 111a to directly suck the air inside the storage space, and the discharge fan 138 is disposed adjacent to the second opening 111b to be purified. By directly discharging the air to the storage space, the air inside the storage space is circulated through the filter device 130. Accordingly, mechanical convection and circulation of the air inside the storage space are made rapidly, and all regions inside the storage space can maintain substantially the same temperature.

Meanwhile, the temperature control device 150 includes a compressor 151, a condenser 153, an expansion valve 155, and an evaporator 157. At this time, the compressor 151, the condenser 153, and the expansion valve 155 are installed in the installation space of the equipment room 111, and the evaporator 157 is installed on the mounting surface of the storage space. The refrigerant sequentially circulates through the compressor 151, the condenser 153, the expansion valve 155, and the evaporator 157, and the evaporator 157 cools the air in the internal space to a set temperature. The expansion valve 155 and the compressor 151 are connected to each other through the evaporator 157 and the bottom, respectively.

As the evaporator 157 is installed on the mounting surface at the top of the interior space, the air is cooled from the top of the interior space, and the cooled air descends downwards by itself due to the difference in density, so that natural convection occurs in the air in the interior space. Can occur. Therefore, it is possible to induce the air in the storage space to have an overall constant temperature within a short time.

In addition, the filter device 130 may immediately suck in the air cooled by the evaporator 157, purify it, and discharge it back to the storage space. That is, the cooled air not only generates a natural convection phenomenon as described above, but also generates mechanical circulation and convection phenomenon while being circulated by the filter device 130. Therefore, it may be easier to maintain a constant temperature of the internal space.

Alternatively, the first opening 111a is located farther from the evaporator 157 than the second opening 111b, so that uncooled air is sucked in the first opening 111a, and the purified air is the second opening 111b. ) Is discharged through the evaporator 157 to cause a mechanical convection phenomenon in the horizontal direction in the storage space. To this end, a guide line 141 for guiding the air discharged through the second opening 111b to the evaporator 157 may be installed on the mounting surface (see FIG. 5 ).

Meanwhile, the filter units 135, 136, 137 may include a pair of activated carbons 136 and 137 and a clay mineral 135 positioned between the pair of activated carbons 136 and 137.

More specifically, according to an embodiment of the present invention, in the filter unit, a pair of activated carbons 136 and 137 are arranged in the order of a honeycomb shape and a mesh shape, so that the air is large At the same time, it moves toward a small hole in the air to more effectively adsorb harmful gas, and at the same time, due to the suction fan 132 and the discharge fan 138 disposed on both sides of the filter unit 135, 136, 137, harmful gas is removed from the refrigerating chamber. Since it is rapidly inhaled and the purified air can be quickly supplied back to the refrigerating chamber, air from which harmful gases have been effectively removed can be quickly directed to the refrigerating chamber.

Further, the clay mineral located in the filter unit may include one or more selected from the group consisting of natural zeolite, synthetic zeolite, vermiculite and bentonite, and more specifically, natural zeolite, synthetic zeolite, vermiculite, and bentonite are mixed. It may be one.

The clay mineral according to an embodiment of the present invention may be a mixture of 40 to 50 parts by weight of natural zeolite having a particle diameter of 2 to 5 mm and 50 to 60 parts by weight of synthetic zeolite having a particle diameter of 0.1 to 0.75 mm. When mixed within the above weight part range, a high surface area of high clay minerals can be secured, so that acid resistance and high harmful gas adsorption ability can be secured, and at the same time, dense adhesion between particles is possible, so that the filter unit is compact. There is an effect of being able to configure, and when the filter unit is compactly configured, a plurality of filter units can be provided within a limited installation space, so that a plurality of filter units to be described later are formed in a modular structure in which a plurality of filter units are arranged in series. It can be advantageous.

On the other hand, the main body 110 may be provided with a reader unit (not shown) for reading the serial number written on the drug. The serial number may be attached to the medicine in the form of an electronic tag such as a barcode, RFID, or QR code. The serial number may include information corresponding to each drug such as the type, weight, and expiration date of the drug. The reader unit may read information recorded in an electronic tag when a medicine is brought into or out of the storage space. In addition, the control unit may record information (carry-in/out information), expiration date information, etc. of the stored medicines into or out of the storage space in the internal system.

Furthermore, the medicine storage device according to an embodiment of the present disclosure may further include a photographing unit (not shown) provided inside the main body 110. The photographing unit may photograph the interior of the storage space and the path through which medicines are brought in or taken out. In addition, the controller may additionally acquire information about carrying in/out of medicines by storing image information captured by the photographing unit.

Accordingly, the force of the filter device 130 inhaling the air in the storage space and the force of discharging the purified air into the storage space are combined, so that the intake and discharge of air can be performed more smoothly. The flowability is improved, and the speed at which the air in the storage space is circulated increases. Accordingly, the temperature deviation of the gas passing through the filter device is reduced, and the air inside the storage space may be more easily maintained at a constant temperature. In particular, in the case of reducing the temperature deviation of the gas passing through the filter device by the above configuration, it is possible to prevent unreasonable operation of the compressor (compressor) in advance, thereby preventing malfunction or failure of the compressor in advance ( 7 to 9).

Furthermore, since the air sucked into the filter device passes through the filter unit as described above a plurality of times, the harmful gas removal effect can be maximized.

The number of filter devices that can be included in the filter device of the above-described modular structure can be selected and selected as needed, and the arrangement in series means the suction fan 132 provided in one filter module and the other filter module.
